You are given an array of n integers. Your task is to calculate the bitwise or of each window of k elements, from left to right. In this problem the input data is large and it is created using a generator. Input The first line contains two integers n and k: the number of elements and the size of the window. The next line contains four integers x, a, b and c: the input generator parameters. The input is generated as follows:
